Codes: AC9M3N01, AC9M3N03, AC9M3N05, AC9M3N06, AC9M3A01. Target: sample place-value reasoning and an additive problem; name a next practice step. Set out: Check B, number builder, quiet station.
- Purpose · 2 min. Say: “Today I want to see your model and your check. You can change your answer if you find a reason.”
- Rehearse · 5 min. Together represent 15 204 and solve 24 + 18 = 42. State that the new prompts, not this review, will be recorded.
- Place task · 6 min. Everyone builds 14 307 and chooses the larger of 14 307 and 14 370. Ask for the first different place. Quietly sample scheduled focus learners and note help.
- Problem task · 7 min. Read: “There are 346 tickets in one box and 178 in another. How many tickets altogether?” Children estimate, model, solve 524 tickets, then write/show an inverse check. Let classmates work independently while teacher samples; collect work before a shared answer.
- Feedback · 3 min. Respond to actual work: “Your estimate was in the right hundreds. Let's revisit the ten exchange that changed your exact answer.” Choose a model to practise next.
- Close · 2 min. Learners indicate a strategy they want to reuse. Mark
independent / with a prompt / not yet observed; a correct peer-copied number is not individual evidence.
Access and time: one teacher cannot privately hear every child in this 25-minute block. Rotate short 3–4 minute interviews across Days 8–10 or a later station. Do not turn the result into an end-of-year judgement.
